DUMPING SCOW.

SPECIFICATION forming part of Letters Patent No. 678,657, dated July 16,1901.

Application filed January 21, 1901. Serial No. 44,092. (No model.)

To ctZZ whom it may concern.-

Be it known that I, J OHN Mnnsron Goon- WIN, a citizen of theUnited'States, and a resident of the city of New York, borough ofManhattan, in the county and State of New York, have invented a new andImproved Dumping Scow or Vehicle, of which the following is a full,clear, and exact description.

This invention relates to improvements in dumping scows, vessels,vehicles, bins, wagons, or the like; and the object is to provide adevice of this character with a simple means for causing the dischargeor unloading of the scow, vessel, or the like which will not careen, andwhich has cargo-carrying compartments substantially \l-shaped incross-section.

I will describe a dumping-scow embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is an end elevation of a dumpingscow embodying my invention.Fig. 2 is a top plan view. Fig. 3 is a cross-section of a vesselembodying my invention. Fig. 4 is a partial side elevation thereof. Fig.5 is a side view of a detent employed. Fig. 6 is a cross-section of aportion of the vessel, showing methods of supporting the discharging andreplacing devices. Fig. 7 is a side view of a device for supporting oneside of the side valves and swinging the same when discharging. Fig. 8is a top plan view of detents, a detent-shaft, counterweights, andshowing methods of attaching same to the bulkheads. Fig. 9 shows sideelevations and top views of a replacing-hook employed, and Fig. 10 showstop and side views of a replacing-link employed.

The dumping-scow comprises a body portion 1, divided by verticalpartitions 2 into a series of independent compartments, the

bottoms of all these compartments being inclined downward, and eachbottom comprises one or more center valves 3 and downwardlyswinging sidevalves l. The upper edges of the side valves are connected to thevertical side pieces 5 of the body by means of barhinges 6, and, asshown in the drawings, Fig. 7, two bar-hinges 6 are arranged together,

or, in other words, the hinges are arranged in pairs, mounted to swingon a longitudinally-extended bar or hoisting-shaft 7. The twohinge-sections are connected at the lower end by a pivot-pin 8, whichpasses through a keeper 9, attached to the outer side of the valve l.

As here shown, the body is supported on two scows or vessels 10, therebeing a space between these vessels through which the cargo may bedischarged, as will be hereinafter described. It is to be understood,however, that while I have shown the body as mounted on scows it may bemounted on stationary supports or on wheels.

The center valves 3 are connected to V- shaped struts 11, which at theirlower ends or apexes are provided with rollers 12. These struts aremounted to swing on a rod 13, extended longitudinally through the bodyand at the lower portion thereof, and extend ed lengthwise of the bodyunderneath the 'rod 13 and laterally thereof are center-valvereleasingshafts 14. Connected to these shafts 14 are detents 15. These detentshave curved bearing-surfaces, the sides of which are provided withflanges to prevent lateral movement thereof in relation to the rollers12, which are extended to bear upon the curved surfaces of thesedetents. The several detents on a shaft or rod. 14 are of varyingwidths-that is, the detents for the second compartment will have abearing-surface twice that of the detents for the first compartment, andthe detents carrying the cen-' ter valve of the third compartment willhave a bearing-surface three times that of the first compartment, and soon throughout all the compartments there may be in the body. This is toprovide for unloading the several compartments one after the other-thatis, by rotating the shafts 14 all the detents will be moved; but all ofthem except the first will remain in engagement with their rollers 12,while the first ones become disengaged from their rollers, allowing thecenter valves and side valves to fall. It will be noted that the inneror free edges of the side valves when in closed position rest upon theouter edges of the center valves. After discharging the firstcompartment the shafts are to be still further turned to release thevalves of the second compartment, and so on until all the compartmentsare discharged. I will state here that while the above description mightindicate that the valves of both sides are operated together, it is tobe understood that the valves of one side only may be opened, while theothers remain closed, depending upon the side of the vessel from whichthe load is to be discharged, or, as will hereinafter appear, the loadmay be discharged between the two scows or vessels 10.

Arranged at opposite sides of the body portion are short chutes 16, andto these short chutes auxiliary chutes 17 are hinged so that they maybeswung upward against the body when not in use. WVhen in use, however,these swingiiig chutes 17 will be lowered, as indicated at theright-hand side of Fig. 3, so that the load will discharge over thesame. In the upper portion of each fixed chute is mounted to swing aretarding valve or plate 17 This retarding-plate has its end wallspivoted to the sides of the chute 16, and its front plate may be loweredmore or less into the discharging material.

Arranged to close the space between the lower edge of a valve 3 whensaid valve is in its open position and the upper end of the fixed chute16 is an auxiliary valve 18. This auxiliary valve 18 is made in the formof a plate and is mounted on spring-yielding hinges 19, which swing onrods 20. These hinges not only permit the swinging of the said valves18, but, being yielding, form buffer-abutments for engaging with thevalves 4 when they are swung to their open position, as indicated at theleft-hand side of Fig. 6.

When the said auxiliary valves 18 are open,

as shown at the left-hand side of Fig. 6, the material discharged willbe directed between the vessels or scows 10, the said open valves 18forming stops and directing-valves. The valves 18 are moved byhand-power to their open or closed position.

A hoisting arrangement for the purpose of replacing the center valvesand side valves to carrying position consists of a hoisting-shaft 7,mounted on the side of the vessel, one movable pulley-block 22, a chain23, connected at one end to the upper portion of a partition andextending around said pulley 22 and thence around a fixed pulley 24 andto the shaft 7, which may be turned by any suitable means. Connectingwith the two divergent members of the chain 23 are hoisting-hooks 25,adapted to be by hand placed in engagement with links 26, connected tothe valves. The novel formation of the hoisting-hooks 25 allows them todisengage themselves from the links 26 by gravity when the strain ofhoisting is releasedthat is, each hoisting-hook has a weighted extension27, which will rock the curved surfaces 28 of the hooks on the upperside of the valves when the hoisting strain is released, and when thisstrain is released the hooks will move downward until they come intoengagement with the valves. Then the weighted ends will cause said hooksto swing outward out of engagement with the links 26, as it will benoted that the chain 23 is on an incline when the hooks are in theirholdingposition. When the hooksare byhand placed in connection with thelinks and the chains drawn taut, the weighted ends of the hooks will bedrawn upward, causing the forked members of the hooks to engage theinner and outer surfaces of the eyes, so as to hold tightly when liftingthe valves. The links 26 are mounted to slide in openings in thevalves,so that when said valves are swung to their open position thesaid links at their inner ends will be practically flush with the innersurfaces of the valves. By the use of the movable pulley 22 thehoisting-power be comes double that usually obtained by the use ofthe-fixed pulleys. Therefore it is feasible to raise both the centervalves and the side valves at the same time. The branches of the chain23 must be of such length and attached at such points to the main chainthat the side valves precede the center valves just before reaching thecarrying position, as indicated by the dotted lines in Fig. 6. In otherwords, this is to prevent the closing of the side valves before thepassing of the ends thereof over the ends of the center valves whilesaid center valves are moving to'closed position.

Attached to one end of the shafts 14 are arms 29,provided at their freeends with slots, through which a pin projecting from thevertically-operating bar 30 extends. This bar 30 is provided with apiston adapted to operate in a cylinder 31 and by means of which rockingmotion may be imparted to the shafts 14. The chutes 17 may be raised andlowered by means of chains 32, and it will be noted that the outer sidesof the struts 11 are provided with teeth 33, with which a crowbar orother device may be engaged to start the valves should they becomefrozenor otherwise tem porarily locked.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
